IHERON FROST, OF PIERMONT, NEW YORK..

Specification forming part of Letters Patent No. 136,232, dated February25, 1 3.

To all whom yit may concern:

Be it known that I, THERON FROST, of Piermont, in the county ot'Rockland and State ot' New York, have invented a new and ImprovedCombined Sash Fastener and Tightener, and-I do hereby declare thefollowing to be a full and exact description of the same, referencebeing had to the accompanying drawing forming part of thisspecification, in which- Figure l is aperspective viewr from the rearside ot' the apparatus. Fig. 2 is a transverse vertical section, and 3 atop view ot the lower sash-plate.

Similar letters ot' reference in the accompan ying drawing denote thesame parts.

The object ot' this invention is to combine a sash-lock and ananti-rattling device for windows in one simple, cheap, and convenientimproved article of manufacture; and to this end the invention consistsin the improved construction and combination of parts, substantially asI willnow proceed to describe.

In the drawing, A is the lower` rail of the upper sash, and B the upperrail of the lower sash. G is the plate for the upper sash, and D theplate for the lower one. The plate C is screwed directly to the upperside of the rail A, and has a vertical iiange, c, extending` upward fromits inner edge and tlush with the inside ci the rail. To the outer sideof theiiange c is secured, in any sufficient manner, a case, D', inwhich is pivoted a latch, E, which latch has a tooth, e, with aninclined upper edge, and extending inward through a slot in the Han gec, and kept in this position by the weight of the latch, except whenthrust backward. The plate D is screwed directly upon the upper side ofthe rail B, flush with the outside thereof, so that when either Atheupper sash, having been lowered, is raised, or the lower sash, havingbeen raised, is lowered,- the inclined tooth e comes in contact with theedge of the plate D, and is moved back. At'- ter clearing the plate Dthe tooth e moves out again by its own weight over the plate, and thuslocks the sashes. The tooth e is constructed with a shoulder, e, asshown in Fig. 2, which bears lagainst the tlan ge c, and takes from thepivot ofthe latch part of any strain that may be exerted upon thelatter, either by pushing up on the lower sash or pulling down on theupper. F are lugs extending backward from the ends of the lower plate,and curving inward toward each other so as to form grooves -z of suchwidth that the flange c lits them closely when both sashes are closed,so that these lugs preventrattling of the sashes.

A step, a, rising from the plate D ills the space between the latter andthe-tooth e, and thus insures a tight lock.

The parts ot this device may be cast or struck out of any suitablemetal.

Vhat I claim as new is- As an article of manufacture, the combined sashfastener and tightener herein described, consisting essentially of theplates C D, constructed, respectively, with the slotted flange c andlugs F, the case D', and the tooth E, constructed with the shoulder eand tooth e, all combined as described.

THERON FROST.
